With these 'and 1ctflf1er-cbjects and advantages in viewthe invention, consisting in the construction, combination and novel arrangements or parts, will be clearly understood from the following description, reference being had to the accompanying drawing which forms a part of, this application and in which like characters of reference indicate corresponding parts throughout the several views, of Which,-

Referring, now, to the illustrations, 9 represents the stock of a mechanics level resting upon a straight edge, 10. At opposite ends of 'the level stock I mount on the straight edge one of my devices, preferably including a metal bar, 11, the end portions of which are downwardly offset', as at 12, to rest upon and be secured to the vstraight edge as by screws, 13, thus leaving the intermediate portion of the bar spaced from the plane of the supporting end portions, 12.

The Supporting portions, [12, effzthe basare relatively narrower than the intermediate. portion, and the-end 4portion,12,`remote' from `the level is formed on', ppste vsides.

the 'straightV edge, andthe "pilates, "18, slid in the direction of the level, thereby forcing thecfree end portions of the wires, 16,V

toward each other, 'causing the Aprojecting parts, 17, to engage the end portions of the level stock, or in openings, 20, in the said stock. Obviously, to 'detach the leyel Vfrom the straightV edge it is only necessary to slide the plates, 18, from the level stock, thus causing the wires, 16 to springfout- .wardlyr and thus disengage the stock.y

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is,-`

1. A clamp for removably securing a level Stockto a straight-edge, including an elongated plate, having'supporting means to tjbelgoijv the'fedgee-Orthe Y be secured to the straight-edge and hold the plate spaced from'the straight-edge, a U- shaped spring wire having its web disposed u transversely of the plate, and its arms extended along the sides of the plate, the free end portions of the wire tending to spring outwardly from each other, and engageable,

when forced toward each other, with the `stock toa straight-edge, including an elongated plate having offset end port-ions tov be secured toV the straight-edge, a U-shaped spring wire havingi its web disposed transversely of the plate and its arms'extended along the sides of the'plate, the free end portions of the wire tending to spring from each other and engageable whenforced toward each other, with theA level stock, and an element across the plate having grooves to freely receive the arms of the wire and the opposite sides ofthe plate, whereby the wire may be engaged and disengaged with and from thestock by accordingly sliding said element toward and from the stock.

3. A' clamp for removably securing a level stock to a straight-edge, including an elongated plate having reduced and 'offset end portions to be' secured to the straightedge, a U-shaped spring'wire having its' web 'disposed transversely of the, plate and its of the wire and the opposite sidesof the,

plate, whereby the wire may be engaged and disengaged with and from the stock by accordingly sliding said element toward and from the stock.

4. A clamp for removably securing a level stock to a straight-edge, including an elongated plate having offset end portions to be secured to the straight-edge, eyes formed on Vopposite sides of one of said end portions, a

U-shaped wire having its web extended through said eyes, and its arms extended along the sides ofv the plate, the freevr end portionsof the arms being extended from the plate and having a tendency to spring from each other, and adapted when `forced toward each other to engage the level stock, and an element across the plate having grooves to freely receive the wire and the opposite sides of the plate, whereby tliewire may be engaged and disengaged withand from the stock by accordingly sliding said element toward and from the stock.

In testimony whereof I havehereunto set my hand this 28 dayof April, 1922; Y
